Build a community - Connect with like minded people/readers to know what they expect out of you. Interact with them at regular intervals and take their feedback. It will help you gauge a trend and hint you towards a direction you want to take your blog to.

Add your personality - If you are writing on a particular topic, there are a number of people who will be writing on the same topic. So you need to add that specialty to your blog to make it look different and to allow your readers to take away something that the others are not offering.

Use technology - Social plugins and SEO tools are a great thing to market your blog or a blog post. If you do not know about it, then learn it. It helps you reach out your audience in a better way and also improves the ranking of your blog.
